Technical field
The present invention relates to a kind of gasket seal and manufacture method thereof, relate in particular to a kind of laminated closed seal spacer and manufacture method thereof.
Background technique
In the prior art, gasket seal is many to be made with materials such as asbestos, rubber, because the ability that this kind material meets with stresses is relatively poor, in use for some time, owing to bear the effect of pressure and ambient temperature, gasket seal is easily aging or lax, sealing variation even lose sealability, flexible when mounted distortion has simultaneously influenced sealing effect.The gasket seal that other has metallic material to make, limited because of the metallic material compression recovery performance, Applicable scope is narrower.
Summary of the invention
Thereby the object of the invention is exactly to provide a kind of gasket seal and manufacture method thereof that realizes the compression to Sealing, rebound degree adjustment enhancing anti-pressure ability for solving the deficiencies in the prior art.
Technological scheme of the present invention is: a kind of laminated closed seal spacer, it comprises two folded relatively up and down metal rings that are provided with, is installed in coating on the lower surface of the upper surface of upper strata metal ring and lower metal ring respectively, has the gap between described two metal rings, and described two metal ring inner rings and outer ring connect fixing, be filled with the hard packing in described gap, the filling density of described packing is less than 10 gram/cubic centimetres greater than 0 gram/cubic centimetre.
To the variation of this technological scheme be explained as follows:
1, described packing is one or more the composite in carbon steel, stainless steel, copper, aluminium, Monel (Monel), the severe nickel of English (Inconel), titanium, graphite, fiber, teflon, the resin.
2, offer the pressure guide hole that is connected with described gap at least one described metal ring inner ring, the bore dia of described pressure guide hole is 0.1～10 millimeter.
All offer pressure guide hole on described two metal rings, and have 1～5000 pressure guide hole on each metal ring.
Described pressure guide hole distributes in the inner ring equal intervals of described metal ring, by pressure guide hole is set, utilizes pressure medium that the gasket seal performance is played self-strengthening, the stabilized seal specific pressure.
3, described coating protrudes from 0.1～10 millimeter on the surface of metal ring.
4, welding is fixing mutually with the place, outer ring for described two metal ring inner rings.
The present invention also provides a kind of manufacture method of laminated closed seal spacer, is used to process the gasket seal with above all technical characteristicss, and this manufacture method comprises the steps:
(a), two metal rings are folded relatively, and leave the gap between two metal rings;
(b), in described gap, fill the hard packing, make packing filling density for greater than 0 gram/cubic centimetre less than 10 gram/cubic centimetres;
(c), connect two profiled metal ring inner rings and outer ring fixing;
(d), on the lower surface of the upper surface of upper strata metal ring and lower metal ring, coating is installed respectively.
Described step (c) is offered 1～5000 pressure guide hole along the inner ring of two metal rings afterwards, and makes the aperture of each pressure guide hole at 0.1～10 millimeter.
In the step (b), described packing is one or more the composite in carbon steel, stainless steel, copper, aluminium, Monel (Monel), the severe nickel of English (Inconel), titanium, graphite, fiber, teflon, the resin.
In the step (c), two metal ring inner rings and outer ring fixedly be to adopt the mode of welding to fix.
In the step (d), when coating is installed on described upper/lower layer metallic ring, make coating protrude from 0.1～10 millimeter on the surface of metal ring.
Owing to adopted above-mentioned technological scheme, advantage of the present invention is: by be filled with the hard packing in the gap of profiled metal ring, and the filling density of packing can adjusted between less than 10 gram/cubic centimetres greater than 0 gram/cubic centimetre, thereby realize adjustment to Sealing compression, rebound degree, strengthened the anti-pressure ability of pad greatly, play better sealing effect, enlarged the accommodation of gasket seal.
Description of drawings
Accompanying drawing 1 is the plan view of laminated closed seal spacer of the present invention;
Accompanying drawing 2 is the amplification profile at A-A place in the accompanying drawing 1;
Wherein: 1, metal ring; 2, coating; 3, pressure guide hole; 4, gap; 5, packing.
Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail.
Referring to accompanying drawing 1 and accompanying drawing 2, a kind of laminated closed seal spacer involved in the present invention, it comprises two folded relatively up and down metal rings 1 that are provided with, is installed in coating 2 on the lower surface of the upper surface of upper strata metal ring 1 and lower metal ring 1 respectively, have gap 4 between described two metal rings 1, and the welding of described two metal ring 1 inner rings and the place of connecting, outer ring is fixing.
In described gap 4, be filled with hard packing 5, the filling density of packing 5 is less than 10 gram/cubic centimetres greater than 0 gram/cubic centimetre, and described packing 5 is selected carbon steel for use, stainless steel, copper, aluminium, Monel (Monel), the severe nickel of English (Inconel), titanium, graphite, fiber, teflon, the composite of one or more in the resin, by in the gap 4 of metal ring 1, packing 5 being set, and filling density may command, thereby realize Sealing is compressed, the adjustment of rebound degree, reach different usage requirements with this, thereby enlarge the accommodation of sealing pad.
The upper and lower surface of sealing pad is its sealing surface; coating 2 promptly is arranged on the sealing surface respectively; and coating 2 protrudes 0.1～10 millimeter on metal ring surface; the material of this coating 2 can be selected one or more the composite in graphite, fiber, teflon, the resin for use, is using when installing, and gasket seal is between the flange of butt joint pipeline; coating 2 contacts with piping flange; play the effect of seal action and protection metal ring, this is common installation method, no longer gives unnecessary details with accompanying drawing at this.
Offer the pressure guide hole 3 that is connected with described gap 4 near the inner ring place at least one metal ring 1, the bore dia of described pressure guide hole 3 can be in 0.1～10 millimeter scope, Fig. 2 is preferred embodiment of the present invention, promptly on described two metal rings 1, all have pressure guide hole 3, offer 1～5000 pressure guide hole 3 on each metal ring 1 respectively, pressure guide hole 3 distributes in the inner ring equal intervals.When being installed in the sealing pad between the piping flange, pressure in the pipeline can be through in the gap 4 between the pressure guide hole 3 importing double layer of metal rings 1, be subjected to pressure in the gap 4 to increase metal ring 1, thereby when sealing surface external force changes, come sealing surface pressure is compensated by the pressure medium transmission, with the seal pressure of stabilized seal pad, realize self-strengthening.
